Exochomus quadripustulatus, commonly known as the pine ladybird or pine lady beetle, is a species of beetle of the family Coccinellidae. Exochomus quadripustulatus can reach a length of about 4-6 millimeters. It is almost circular, convex and shining, with a flange around the base. The color is quite variable and may change with age. Usually the elytra are black with two larger red comma-shaped spots and two smaller round red spots. The color of these spots can also be orange or yellow, but completely reddish brown specimens may occur.
This species is present in most of Europe, in the eastern Palearctic, and in the Near East. It was first recorded in Ireland (County Armagh) in 2014. It was introduced to San Francisco between 1915 and 1930 to control the hemlock woolly adelgid, and has since spread across the west coast of North America from California to British Columbia. It is also present in Massachusetts.
This fairly common ladybug can be found from April to October especially on conifers and in areas with deciduous trees. The pine ladybird in both adult and larval stages preys on aphids and scale... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Pine Ladybird is recorded against all the insects logged in Prague (42 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
